To all wkom/ it Trl/wy concern.-

Beit known that I, FREDERICK W. GORDON,

a citizen of the United States, residing at Hartford, in the county ofHartford and State 'of Connecticut, have invented certain new and usefulImprovements in Turbines, of which the following is a specification.

My invention relates to improvements in turbines, and hasl for itsobject the provision of a machine of that class which will be simpletion opposite to that of the first-named set..

A further object of the invention is the pro- Vision of connected setsof blade-carriers alternately arranged with relation to each other,

one set moving in one direction. and the other set in an oppositedirection.

Further objects o-f the invention will be hereinafter set forth.

In the accompanying drawings, Figure 1 is Y a longitudinal verticalsection of a turbine embodying my improvements, parts being shown inelevation. Fig. 2 is a side elevation of one of the blade-carriers,taken on line a a of Fig. 1 looking in the direction of the arrow, thecasing being omitted and the bearing and shafting being represented insection. Fig. 3 is a diagrammatic view representing the blade-carriersand the guiding-ribs, the ribs and blades being in section. Fig. 4v is alongitudinal vertical section of three of the blade# carriers ofmyimproved turbine, showing the manner in which they are assembled. Fig.5 is a longitudinal vertical section of two of the blade-carriersdetached, showing them keyed to the shaft which is tted in the tubularshaft of Fig. 4; and Fig. 6 is a diagram showingv the mode of operationof the improved turbine. l

kReferring to the drawings, the numeral 5 designates a casing in whichrmy improved machinel is mounted, said casing rising from a base 6.

In the construction illustrated in Fig. l the invention is shown adaptedfor use as a rotary pump or as a blower to which Huid is suppliedthrough a port 7, leading to a suitable source of supply.

In a bearing 8 of the casing is journaled a tubular shaft 9, to which apulley or equivalent element 10 may be secured. Either integral with orsecured to the shaft 9 is a carrier 12,.hav.ing a chamber 12', in whichare blades 13 ofv parabolic form, each blade being brought to a sharpentrance end 13" and terminating at its other extremity in a linesubstantially parallel to the axis of the carrier. Any requisite numberof theseblades may be employed; but I have found about twenty to beuseful invaccomplishing the result required. Designated by l4'is a drumwhich projects from the carrier 12, and this drum may either be integralwith or. detachably secured by bolts or otherwise, as at 14', Fig. 4, tosaid carrier. Adjacent to the carrier `12 is a second carrier 15, havinga chamber 15' provided with a 'series of parabolic blades 16, preferablyabout forty in number, and having delivery ends substantially parallelto the axis of the carrier, but spaced at a less distance apart than arethe blades 13 of carrier 12.

This carrier 15 is keyed or otherwise secured at 152 to a shaft 17,mounted in the tubular shaft 9,' said shaft being equipped with a pulley18 or other element to which power may be applied, and said carrier isalso provided with a projecting hub 153 for a purpose hereinafterstated. Keyed to drum 14 at 19 is a third annular carrier 20, having achamber 20 Aadjacent to its periphery, in which are located .twentyl ofdownwardly curved parabolic blades 22-,5the1 .delivery ends of wh-ichare sub-y -stantiallyiparallel tothe axis of--the carrier', .Thiscarrier has ahub 213, which when the parts are assembled abuts againstthe vhub 153ofcarrier 15, therebypacingsaid carriers and 21apartasucient distance to receive between ,them the carrier 20, asillustratedin Fig. 1. yDesignated by 23 is a fifth carrier, which is ,1okeyed to the drum 14 at 23 and is provided d `,with a chamber 232adjacent to its periphery; In said chamber are located upwardly-curvedblades 24 of parabolic form, preferably about one hund-red and siXty'innumber, although 15 the invention is not limited inithisA respect;-

The delivery ends of these blades are also substantiallyparallel `to theaxis of, the carrier. Fromthe abovedescription it willbe seen thattheconnected carriers 12, l2O, and23 ro- 2o tate in the direction of thearrows 30 andthatI the setofcarriers A15 .and 21 rotatesinthedirectionofthearrows 31and thatthe parabole blades ofthe.earriers12, 20, and 23 are eurvedupwardly, ,while thei parabolic bladesof the carriers 15 and 21 are curved down.-

wardlry, `the resultbeingthat ,two sets of oppositelyrotatinglblade-carriers are provided,

thel purpose of which.. willbeset forth in the.-

driven by saidshaft in lthe direction of the arrow in Fig. 1, and. topulleyorother ele 4o mentg18 `to rotate. it and thecarriers 15 and21 inthe oppositedireetiomr .that of .thearrowi 31..- in said.; figure. When.the machine is started.the1 casing 5 is supplied with liquid throughport7, and, as willbeobserved,owing to theparabolicshapeof theblades 13.0fcarrier 12, they will .readily engage fluid, within saidy casing, carryit upward andI thendown-V ward and. .force it in an axial directiontoward the. outlet35,.while theparabolic bladeslof 5ocarrier-15,.whiehirotates inan opposite direc-` tion, to thatof carrier12 `Willtalie` the. fluid delivered by theblades ofsaid carrier 12,carryit downward. and.; upward. andV force it axially. forwardatisubstantially double @the velocityv at vwhich. it is propelled bythe. blades13. Themtheblades 2()2 of carrier,20, rotating. vinthesamedirection as carrier,12, will receive thefluid ,from .blades13,will carry it upward andL downward andiforcibly deliver it axially 6oof. ,the.casir1g` at l further .augmented velocity.

Then theblades 22 of carrier ,21, rotating in.

unisongyvith lcarrier 15 (see Fig. .5) and in an oppositedirectiontothatof carriers 12.and 20, will engagetheuid, carry-it downwardandiipward and. forcibly expel Ait at greaterl velocity than it had whenleaving carrier 20 and, finally, the parabolicv blades 2-1 of carrier23, rotating conjointly with carriers 12 and 20, as shown in Fig. 1,will seize the liquid, carry it upward and then downward and inipel itaxially forward at greater velocity than it issued from; the. blades 22,and from isaid carrier-'23 the liquid4 is forced-between theguide-blades 34 and to4 theconical shell 33, from which it escapes bythe nozzle-opening In this way the velocity of the fluid is constantlyaugmented as it travels to its discharge-opening, and while l have shownlive alternately-arranged carriers, three of which rotate in onedirection and two in the opposite direction, it is to be distinctlyunderstood that the inventionis not limited in this respect, for anydesired numberof said carriers may .beemployedg nor-is it limited tothepar.- tieularshapeoinspecific number of bladesr in thel carriersshown, .forl modificationsl may be made without Ldeparture Y fromy theinvention .i

and 'N show the resultant'effectof the owof f liquid from the blades ofsaid carrier. So, too,

the lines O, P, and Q illustrate the resultant effect of the fluid whendelivered by the parabolic blades 24' of the fifth carrier 23, should itbe employed. From what has been stated it will be seen that the currentflowing from one carrier is picked up without shock or blow by theparabolic blades of the next carrier at its own velocity, and so on,constantly increasing in velocity by thefparabolic blades of thesucceeding carriers until it is delivered into the conical' shell by thelast set of parabolic blades. By arranging the blades in the mannerdeleaves the blades of the last carrier and is forced by 'them betweenthe'guide-blades 34 and into the conical nozzle 35. rIn all priorconstructions of which Iam aware the vresultant effect isfdiiferentfromthat accom` plishedy by vmy improved turbine. In said priorconstructions, whether employed as blowersor as turbine water-wheels,parabolic blades have not been employed andtheiblades have either beensoinclined or so curved that they cannot accomplish the result attained byFurthermore, the `blades of these old constructions have neitherdiffered in height nor in number, and consequently Ahave been unable toaccomplish the result herein set forth.- As will be observed from Figs.land 3, the

' variousblade or vane carriers are fitted closely together and yetwithsuiiicient clearance to enable them readily to pass each other, and

by surrounding the carriers 15, 20, 21, and

thereto by key 19 or otherwise. Carrier'21isl then vslipped upon. shaft17 and secured in place. Carrier 23 is then keyed to drum 14 at 23, and,finally, the conical shell 33 is attached to the open end of the casing.

Blades the working surfaces of which are drawn on parabolic curves causean important improvement in the result, for the 4entrance ends 13 ofsaid blades cleave the liquid, and the. delivery ends, beingsubstantially parallel to the axis of the carrier, drivesaid liquidforward in an axial direction, whereby tions may be made in thisrespect.
